Summary
  • If your clutch pedal is stuck to the floor, you’re likely dealing with a broken clutch cable, low clutch fluid levels, or a damaged clutch release bearing.
  • In some cases, a faulty slave cylinder or a defective master cylinder can also cause your clutch pedal to stick to the floor.
  • If your clutch suddenly fails, look for a safe place to park, and call for roadside assistance. Ignoring the issue and continuing to drive can cause an accident. Of course, if the clutch remains engaged and can’t be released, you won’t be able to keep driving the car anyway.

Everybody who drives a manual transmission vehicle knows you have to release the clutch before you can put the vehicle in gear or shift to the next gear.

The most typical clutch failure is when the clutch slips rather than engaging, either because the clutch needs to be adjusted due to the disk lining getting thinner (which causes the pedal to have less free play) or because the disk lining is completely worn out.

On most manual shift vehicles built over the past 25 years, the pedal is connected to the clutch by way of hydraulics rather than a clutch cable or mechanical linkage. If the clutch linkage or hydraulics fails, the clutch pedal will press freely and swing on its mount rather than releasing the clutch, and, in some cases, it may stay all the way down instead of returning to the top of its travel.

Why Is My Clutch Sticking to the Floor?

There are a few possible causes. Here are some examples:

Broken Clutch Cable

In non-hydraulic clutch systems, the clutch pedal is connected to the clutch fork and bearing using a wire rope style cable that runs through a flexible steel housing surrounded by a plastic sheath.

The housing is anchored on both ends, and when the clutch pedal is applied, the cable slides in the flexible steel housing tube so that the clutch is released when the pedal is depressed.

This type of clutch will have a throwout fork at the transmission passing through the side of the bell housing into the clutch chamber.

The throwout fork moves the clutch release (throwout) bearing to press the fingers on the pressure plate (clutch cover), which, because of their design, removes the pressure applied to the disk by the pressure plate springs so the clutch cover and flywheel can rotate without rotating the transmission input shaft, which is splined to the clutch disk.

If the cable becomes disconnected, the pedal will be very loose with no resistance and may go to the floor unless the pedal has a spring to hold it at the top of its travel. If the cable binds or the housing kinks or breaks, the pedal may be very stiff so that it can’t release the clutch, which is the opposite of the pedal going to the floor.

Low Clutch Fluid

Clutch fluid is pumped from the master cylinder to the slave cylinder when you step on the clutch pedal, which allows the clutch to release from the flywheel. If there’s a leak in the system, the clutch fluid can drop to low levels, causing your pedal to stick to the floor.

Fluid doesn’t compress, but air does – that’s why the air must be bled out of the system for any hydraulics to work. The clutch hydraulics must be free of trapped air. | Image Source: Richard McCuistian

Damaged Clutch Release Bearing Guide

Also known as the throw-out bearing, the clutch release bearing moves on a collar that doubles as a bearing retainer for the input shaft bearing on the transmission.

Newer vehicles have a “concentric” slave cylinder that is hydraulic and they don’t move on this collar, but older release bearings do. If the collar is worn (see photo) so that the release bearing doesn’t move smoothly, the collar must be replaced. | Image Source: Richard McCuistian

Defective Clutch Master and/or Slave Cylinder

In a hydraulic clutch, fluid may leak due to loose seals and hoses, but more commonly, the cups and seals in the master cylinder or slave cylinder can fail.

Is It Safe To Drive With a Sticky Clutch Pedal?

No, it isn’t. If your clutch pedal is sticking to the floor, it’s only a matter of time before full clutch failure. The loose clutch cable could snap, or the springs behind the pressure plates might fail, preventing you from moving your car. If any of these components fail while you’re driving in heavy traffic, you could crash into another vehicle. For your own safety, it’s best to avoid driving until you fix your sticky clutch pedal.

What To Do if Your Clutch Suddenly Fails

Whatever you do, don’t panic. Here are some tips on how to safely stop your vehicle if your clutch suddenly fails:

Stop Driving

If you’re driving on a busy road, look for the nearest spot where you can safely park your vehicle. Switch off the engine, and turn your hazard lights on to make yourself more visible to other drivers.

Call for Help

If your insurance covers roadside assistance, you can ask them for help. You can also call a towing service to help bring your car to the nearest mechanic.

How Does a Clutch Pedal Work?

Stepping on the clutch pedal drives the clutch release bearing against the spring, relieving the pressure clamping on the pressure plate. This allows the engine to disengage from the transmission, letting you switch gears. If the clutch pedal gets stuck on the floor, you likely won’t be able to change gears.

How Long Does a Clutch Last?

Clutches can last anywhere between 30,000 and 100,000 miles. Their lifespans can vary depending on several factors, especially one’s driving habits. Rapidly changing gears, riding the clutch, and driving up and down steep roads can all cause your clutch to wear faster.

How Much Does a Clutch Pedal Cost?

The final price will depend on several factors, including your vehicle’s year, make, and model. In general, however, you can expect to pay anywhere from $10 to $60 for a brand-new clutch pedal.
